I own 2 Mehran Euro II 2013, one is VX in smoke green (7,000 kms done to date) the second is VXR in white color (8,000 kms done to date). The VX has upgraded tires from general to Yokohama, whereas VXR is stock.
I was thinking of starting a detailed thread on my experience with the highest selling car in Pakistan but wasn't able to do so due to time constraints. Coming back to the topic, the fuel averages of my cars are as:
16 kmpl in city (definitely w/o AC )
9-10 kmpl in city (with AC)
11-12 kmpl in city (w/o AC)
All driving is with light foot, on rash driving the fuel averages go further down.
